Advancing medicines. Solving problems. Improving lives. Anaphylaxis: A Serious Systemic Hypersensitivity Reaction That is Usually Rapid in Onset And May Be Fatal1 As many as 49 million people in the United States are at chronic risk for acute anaphylactic episodes2 Lifetime prevalence may be higher than 5%3 Chronic allergies cost the United States healthcare system more than $18 billion annually2 52% of patients in a nationwide patient survey who had previously experienced anaphylaxis had never received an epinephrine auto-injector prescription3 60% of respondents in same patient survey did not have an epinephrine auto-injector currently available3 8 References: 1.

Epinephrine Auto-injectors, The Current Standard of Care, Are Challenging Patients and caregivers using epinephrine auto-injectors often experience fear, anxiety, and needle phobia1,2 – Needle fear has been reported in 68% of children aged 6 to 8 years and 65% in children aged 9 to 12 years3 – Fear acquired in childhood appears to persist into adulthood4 – Additionally, some patients (or their caregivers) may be unable to properly inject the medication5 Severe outcomes and fatalities have been correlated with delayed administration of epinephrine.6,7 Late administration of epinephrine has been linked to greater risk of a biphasic reaction, which is a recurrence of anaphylaxis following treatment for the condition8 9 References: 1.

AQST-109: Potential to Solve These Issues AQST-109 is the first and only orally delivered epinephrine product candidate for the treatment of allergic reactions (type 1), including anaphylaxis, that would allow patients and their providers to: 10 Quickly deliver epinephrine to control emerging symptoms and prevent progression Alleviate the fears associated with auto-injectors and self-injection, including needle phobia1 Prevent improper administration or suboptimal dosing, including associated adverse events such as injection site necrosis and/or infections2,3 Reduce the likelihood of noncompliance or delayed dosing because the sublingual film is small, portable, and can be administered quickly and easily3 References: 1.
